Background
three decades of GIS and spatial
data capture technology
an eclectic range of academic
disciplines using GIS as a
research and teaching tool
considerable cost and time
invested in spatial data creation
*2006 spatial data audit at
4 universities: +500 dataset files,
100s of orphan datasets
Requires a spatial data management,
discovery and sharing solution
delivered through portal technology
and metadata .

So what is METADATA ?
The word appears to be of Greek and Latin origin……
but metadata represents something completely different…… Photographic Images copyright: Jupiter Images 2006

Photographic Images copyright: Jupiter Images 2006 and it’s not sun and holiday

Represents a documented and ordered summary of information that describes something, in this case, a spatial dataset. Provides the What, Where, When and Why of a dataset, Ownership and Contact details and Access and Use conditions. Think of metadata as a recipe for making beer….. What are the ingredients? What are the brewing steps? Who sells the ingredients or W here can you buy them? Purpose of making beer? Metadata (data describing data) Photographic Images copyright: Jupiter Images 2006 An incentive to encourage metadata creation?

Where is the study area
represented in the data?
When were the data collected?
What is the dataset’s purpose?
spatial reference system?
spatial accuracy?
type of application?
processes or algorithms used?
Who supplies the data?
What do these polygons represent?
What attribute information is
associated with these polygons?
So why metadata? Can you tell me from these files…..

What do these SOILCLASS values mean? What does this attribute mean?

These questions can
be answered in one
metadata record

The relevance of geospatial metadata
Useful for local data management
Dataset Creator/ User Metadata Record Spatial dataset Directory Spatial Datasets Metadata Directory

Geoportal : an interface to run searches on the internet to locate geographical resources, and to discover, harvest and publish metadata records representing spatial data and geo services.
A geoportal enables users to search and discover geospatial metadata using
geographic location (co-ordinates and place name)
free text
date
resource type

and developing GIS applications

Other benefits: data protection Photographic Images copyright: Jupiter Images 2006

protects investments of time and cost dedicated to
dataset creation and development;
maintains an inventory of datasets to reduce time required to
re-assess existing datasets for new and future applications;
ensures integrity of existing and new datasets using metadata as a tracking mechanism to monitor changes and edits to datasets;
reduces and minimises the disruptive effects of staff
turnover;
eliminates or reduces the risk of redundancy in dataset collection;
accidental deletion of dataset files.

Intellectual Property Rights (IPR)
residual licensed data rights for derived data
liability fears
concerns over data quality (data creator and user)
privacy and security
time and cost for data delivery
data transformation and harmonisation (scale, positional accuracy, projections, formats)
legacy data
time and cost to anonymise data for release
time and cost for metadata record updates, especially descriptive level metadata
performance, maintenance and enhancements of portals and repositories
data archiving
data and software warehousing issues
long-term commitment and investment in the infrastructure
revisions to standards
confusion about standards compliance and which standard to use
Still issues though!

Metadata standards
provide precise specifications;
enforce and ensure consistency and interoperability;
define and describe metadata entities and data elements;
classify and group relevant metadata elements with entities;
assign structure and conditions (obligations, data type, domain).

Dublin Core (ISO 15836)
Dublin Core: 15 elements to facilitate simple resource discovery in a networked environment (e.g. internet or library)

Geospatial metadata standards
Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM) introduced in mid 1990s for documenting spatial datasets.
ISO 19115 Metadata Standard for Geographic Information was ratified in 2003 and supersedes FGDC.
Geospatial metadata standards are critical for supporting metadata creation and…………………………

Geospatial Metadata Application Profiles
ISO 19115 standard has too many elements (300+)

* An application profile is derived from a standard and represents a reduction of the number of entities and elements. * It should include the core element set of a standard to support interoperability across the wider geospatial community ( Discovery level metadata). * Should include elements for Descriptive level metadata? * It can be extended to include elements which are best suited for a working group’s specific applications. Example: The Biological Data Profile (BDP) An approved profile with additional elements to allow for documenting biological information such as taxonomy , m ethodology and analytical tools . http://www.flickr.com/photos/f10n4/186861991/

Infrastructure for Spatial Information in the European Community (INSPIRE) *European Commission (EC) *European Environment Agency (EEA) *Representatives from Member States (Mapping/GIS) INSPIRE Directive Metadata Guidelines

INSPIRE Directive [2007 /2/ EC]
T argets electronic spatial data and services for environmental information.
Aims to create a European Spatial Data Infrastructure (SDI) based on Member States’ infrastructures, to improve interoperability of spatial information.
These data and services to be delivered through initiatives across Europe.
INSPIRE Regulations 2009 No 3157 came into force on 31 December 2009 and applies to England, Northern Ireland and Wales.
Scotland’s Parliament enacted a complementary regulation which came into force on the same date.
Public authorities will be obliged to produce and keep up to date ‘metadata’ for describing datasets, dataset series and geo services.
Includes UK academia as it must comply with the Freedom of Information Act, 2000.

• Provide metadata catalogues to reveal what information is available.
• Provide online data discovery , view , download and transformation (interoperability) services.
• Licensing arrangements to allow for information sharing, access and use in accordance with state regulations.
• Set up e-commerce arrangements where charging is applicable.
• Introduce monitoring mechanisms to show that information is being made available.
• Introduce co-ordination mechanisms to ensure effective operation of the infrastructure.
Comply with the 34 data specifications in three annexes
(reference geographies, environmental datasets).
INSPIRE Regulations for member states

INSPIRE Metadata Editor and Geoportal

* First released in 2004 to support creation of ISO 19115 and e-GMS compliant metadata - supersedes the National Geospatial Data Framework ( NGDF) * Targeting the UK public sector * 2010: UK Location Programme (UKLP) revised UK GEMINI 2.1 to meet the requirements of the EU INSPIRE Directive. UK GEMINI UK Location Programme (UKLP) is a pan-government collaborative initiative with the responsibility to develop and implement the INSPIRE Directive 2007/2/EC and the UK Location Strategy.

Geo resources for UK academia

UK Academic Geospatial Metadata Application Profile, Version 2 (UK AGMAP 2) UK AGMAP 2 created to support the specific needs of the UK H&FE academic communities. Comprises elements from ISO 19115, UK GEMINI 2 and INSPIRE. Supports documentation of a dataset, dataset series or geo service for the purpose of discovery and description. Mapped to Dublin Core, FGDC, INSPIRE, UK GEMINI 2 and DDI.

UK AGMAP 2 profile for datasets and dataset series Contact details = 7 Drop down lists = 10 Red = Mandatory Green = Conditional 32 mandatory 91 elements

UK AGMAP 2 profile for Geo-services Contact details = 7 Drop down lists = 6 Red = Mandatory Green = Conditional 25 mandatory 40 elements

UK AGMAP 2 Guidelines Contain descriptions and examples to assist metadata creators and Go-Geo! portal users from numerous, eclectic academic disciplines.

Most spatial data information is stored in our heads. We need to move it from there to electronic files. Metadata Creation Photographic Images copyright: Jupiter Images 2006

Why publish metadata on the Go-Geo! portal?
a repository for you to store and manage your metadata thus savings in cost and time;
use metadata to announce your data and applications;
advertise (and sell?) your spatial datasets to other interested parties in academia and in the private and public sectors;
metadata in the portal can be referenced and cited for project proposals;
could be configured as an internal resource to access and share datasets.
